Preparation for the STILLEN supercharger

LiquidZ

For a short period of time, yes. The turbo impeller/turbine
wheel maintain some rotational velocity once the exhaust gases stop flowing. Obviously, once internal friction forces take over, the rotational velocity of the impeller/turbine decreases to zero.

Yes, turbos do add backpressure which can be seen to limit power output, but my point was the turbo requires no mechanical work from the actual engine to spin and produce power. The turbo simply works off of waste exhaust gas, and not the engine itself.

LOOOL I like what you did there, very smart.

You know I wasn't referring to the interial energy stored in the turbo due it being a rotating mass.

I was just saying, to get the turbine spinning, the pistons have to put extra effort to push the exhaust gasses through it. That extra effort would be "robbed" from the engine's total bhp. Where else would the energy come from?

Exactly, the back pressure put by the turbine on the engine "robs" horsepower too you know..

dont the engines need back pressure? Thats why I thought turbos could go bigger diameter exhausts cuz the turbo itself provides the needed back pressure but NA cars have it provided by the exhaust itself.

The energy required to spin a compressor(turbo or supercharger) only comes from one place. That is from the engine itself. Superchargers take the power directly from the crankshaft.
Turbo's get their power indirectly from the extra work the pistons have to do, to force the exhaust past the turbo impeller.

Its only work for the engine at lower rpm, once the turbo spools up beyond inertial forces then any power loss essentially dissapears.

Unfortunatly in the case of a supercharger the faster it spins, the more power it takes to drive the supercharger.

Turbo's don't spin themselves,even after spool up.

What did I start

LOL...LiquidZ had a logical explanation imo but my opinion isn't worth a whole lot lol...

Can't wait to see pics and #'s Kyle!!! I threw up a little earlier with the 90-120 days comment lol Looking forward to any new updates!

Happy Friday all! It's teaser time!

Here's a pic of the PROTOTYPE installed system, we're working on the tuning, and it will be on the dyno as soon as the california monsoon leaves us..



Here's a teaser video of the system as well: STILLEN VQ37 Supercharger Teaser

And here is the reason we weren't driving the G37 today: STILLEN Shop: Hailing

This is not the final kit, the tubes will be polished, etc etc.. but it's running, and we're finalizing everything quickly.

Very cool, Josh! Excited to see what kind of numbers it puts down and what kind of numbers I'll have to put down to pick one up.

is the supercharger in the same location on the 370 or do we get to have it on the correct side as the manifold because we are more important than the g37's?

m4a1mustang

Looks like it will be on the same side for us. There is more available space on the driver's side to house the blower.

Josh: is that the finalized intake manifold design? I wonder if there are going to be clearance issues with the factory strut tower brace.
